Nucleotide Sequence Determination, Subcloning, Expression and Characterization of the xy1LT Region of the Pseudomonas putida TOL Plasmid pDK1Baker, Ronald F. (Ronald Fredrick) 12 1900 (has links)
The complete nucleotide sequence of the region encoding the DHCDH function of the pDK1 lower operon was determined. DNA analysis has shown the presence of two open reading frames, one gene consisting of 777 nucleotides encoding a polypeptide of 27.85 kDa and another gene of 303 nucleotides encoding a polypeptide of 11.13 kDa. The results of enzymatic expression studies suggest that DHCDH activity is associated only with xy1L. However although the addition of xy1T cell-free extracts to xy1L cell-free extracts does not produce an increase in DHCDH activity, subclones carrying both xy1L and xy1T exhibit 300- 400% more DHCDH activity than subclones carrying only xy1L.

THE EFFECTIVENESS OF BIOFERTILIZER ON FIELD GROWN PEPPERS AND GREENHOUSE GROWN TOMATO PRODUCTIONHogan, Patrick Tyler 01 May 2022 (has links)
Biofertilizer (or microbial soil inoculants) may be used to reduce current fertilizer inputs (organic or conventional methods), while maintaining or improving crop plant growth and yield. Pseudomonas putida is a plant-growth promoting rhizobacterium (PGPR) that solubilizes inorganic phosphorous or mineralizes organic phosphates, produces siderophores (enhancing Fe availability for plants, reducing Fe access to pathogenic fungi), and is known to improve plant growth by assisting with nutrient availability, synthesis of plant hormones (indole acetic acid regulation production and/or degradation, or ethylene regulation through aminocyclopropane carboxylate deaminase activity), and acts as a biological control of several plant pathogens and pests (Rhizoctonia solani, Bemisia tabaci). Recommendations for inoculum population density, application timing, and species of PGPR, vary mainly based on geographic and weather conditions, and their relationship to each horticultural crop, which needs to be better understood. Two studies were conducted in 2014 and 2015 at the Southern Illinois Horticulture Research Center to determine the optimum application timing and dosage of Pseudomonas putida strains 17-29 and G11-32 to improve plant growth and yield on two important horticultural crops: field grown ‘Revolution’ bell peppers and greenhouse grown ‘Rocky Top’ determinate tomatoes. Field pepper results indicated that the inoculum population density increased early-season vigor, plant height and stem caliper (P < 0.05), as well as late-season plant vigor, height (cm), leaf chlorophyll index (SPAD), and stem caliper (mm) (P < 0.05) for inoculum population density. Although early harvests (first two harvests) fruit yield increased with rhizobacteria inoculum population density (P < 0.05) for total fruit weight (2014, 2015) and number (2014), late-season fruit yields (last three harvests) were not affected. Combined fruit yield total weight (all five harvests) also increased (P < 0.05) by inoculum population density in the order: 10^0 < 10^3 < 10^5 < 10^7 < 10^9. It appears that higher early-season and combined harvest yields were higher resulting from increasing inoculum population densities were greater due to increased early season growth from the bacterial treatments during plug growth phase. Tomato results indicated that inoculum population density increased early growth and late growth vigor, height (cm), leaf chlorophyll index (SPAD), leaf number, flower number, fresh leaf weight (g), fresh stem weight, and dry leaf weight (P < 0.05). Tomato growth was effected by inoculum population density treatment however, yields differences were not observed.

Creation and Characterization of an Escherichia Coli and Pseudomonas Putida Hybrid Aspartate TranscarbamoylaseRuley, Jill R. (Jill Rosanne) 12 1900 (has links)
Aspartate transcarbamoylase (ATCase) is encoded by the pyrBI genes in E. coli. Expression of these genes is reduced four-fold by attenuation when grown on uracil. Using plasmid, pRO1727. the pyrB and the pyrBI genes from E. coli were cloned into a P. putida pyrB auxotroph. A recombinant pyrB gene was recovered that encoded a functional hybrid ATCase with a molecular weight of 470 kDa.

Vergleichende kalorimetrische Untersuchungen zur Ermittlung der mikrobiellen Aktivitäten von Pseudomonas putidaLißner, Andreas 16 December 2011 (has links)
In der vorliegenden Arbeit wurden Untersuchungen zur mikrobiellen Aktivität von Pseudomonas putida DSM12735 durchgeführt. Als Messgröße diente die mikrobielle Wärmeleistung, basierend auf dem Stoffumsatz durch die Mikroorganismen. Ziel war es, die Vor- und Nachteile der verwendeten Kalorimeter herauszuarbeiten. Dafür wurden klassische Batch-Wachstumskurven aufgenommen.
Ein weiteres Ziel bestand darin, eine Methode zur schnellen kalorimetrischen Detektion der mikrobiellen Aktivität insbesondere für die stationäre Phase zu entwickeln. In dieser Phase findet kein signifikanter Stoffumsatz statt. Durch das gezielte Auslösen einer zweiten Wachstumsphase und damit einem Stoffumsatz wird die mikrobielle Aktivität kalorimetrisch wieder messbar.
Eingesetzt wurden folgende Kalorimeter: der Thermal Activity Monitor 2277 (TAM) mit den Kalorimetern Micro Reaction System 2250-4 ml und 2250-20 ml (kurz: TAM-4ml, TAM-20ml), das IC-Chip-Kalorimeter FCC22 (Institut für Physikalische Chemie, TU Freiberg) und das Kalorimeter Micro-DSC II (MDSC).

Physical and Functional Characterization of the xy1XYZ Region From TOL Plasmid pDK1 and its Associated Downstream Regulatory ElementsHares, Douglas R. (Douglas Ryan) 08 1900 (has links)
The nucleotide sequence for the pDKl TOL plasmid region encoding toluate-1,2-dioxygenase (Xy1XYZ, TO) was determined. TO is the first enzyme in the meta-cleavage operon, responsible for the conversion of toluates and benzoates to their carboxy-substituted diols. DNA sequence analysis revealed the presence of three open reading frames (ORF). The three ORFs correspond to xylX (1353 bp), xylY (486 bp) and xylZ (1008 bp), encoding predicted protein products of 51370 Da, 19368 Da and 36256 Da, respectively.
